-12-+12dB. There are two common methods of parameter tuning: grid search and random search. and more on areas in which it thinks it will gain the most - the range close to zero. Support Vector Machines (SVM), Decision Trees, and Random Forests.

The random forest has a solution to this- that is, for each split, it selects a random set of subset predictors so each split will be different. So more strong predictors cannot overshadow other fields and hence we get more diverse forests. Random Forest Algorithm – Random Forest In R. We just created our first decision tree.

Each of these trees is a weak learner built on a subset of rows and columns. More trees will reduce the variance. Random Forest uses information gain / gini coefficient inherently which will not be affected by scaling unlike many other machine learning models which will (such as k-means clustering, PCA etc). However, it might 'arguably' fasten the convergence as hinted in other answers A random forest is a meta estimator that fits a number of decision tree classifiers on various sub-samples of the dataset and use averaging to improve the predictive accuracy and control over-fitting.

Max_depth, min_samples_leaf etc., including the hyper-parameters that are only for random forests as well. One hyper-parameter that seems to get much less attention is min_impurity_decrease. Random forest algorithm The random forest algorithm is an extension of the bagging method as it utilizes both bagging and feature randomness to create an uncorrelated forest of decision trees. Feature randomness, also known as feature bagging or “ the random subspace method ”(link resides outside IBM) (PDF, 121 KB), generates a random subset of features, which ensures low correlation among decision trees. In random forests, the impurity decrease from each feature can be averaged across trees to determine the final importance of the variable. To give a better intuition, features that are selected at the top of the trees are in general more important than features that are selected at the end nodes of the trees, as generally the top splits lead to bigger information gains.
